Abstract

A method and apparatus for performing a quick search of a path display terminal are provided. The quick search device of a path display terminal comprises: a vehicle position display unit for displaying a position of a vehicle on a map generated based on map data; a quick search display unit for displaying a quick search area for inputting a search word in a portion of the map; a search unit for searching for a destination corresponding to the search word; and a path display unit for generating and displaying a path from the vehicle position to the destination.

Claims

1. A quick search device of a path display terminal, said device comprising a position display unit for displaying a position of the path display terminal on a map generated based on map data, a quick search display unit for displaying a quick search area for inputting a search word in a portion of the map,

a search unit for searching for a destination corresponding to the search word,

a path display unit for generating and

displaying a path from the position of the path display terminal to the destination, and

a speed measurement unit for measuring a moving speed of the path display terminal, wherein the quick search display unit changes transparency to allow the portion of the map, on which the quick search area is positioned, to be seen through the quick search area in correspondence to a moving speed of the path display terminal measured in the speed measurement unit.

2. The quick search device of claim 1, wherein the quick search area displays, along a line, a window for inputting a search word and a search execution button.

3. The quick search device of claim 1,

wherein if a moving speed of the path display terminal measured in the speed measurement unit is larger than or equal to a reference speed, the quick search display unit increases transparency of the quick search area, and if the moving speed of the path display terminal measured in the speed measurement unit is less than a reference speed, the quick search display unit decreases transparency of the quick search area.

4. The quick search device of claim 1, wherein if a search word is input in a designated format to the quick search area, the quick search display unit displays a search method corresponding to the designated format, and the search unit searches for the destination based on the search method.

5. The quick search device of claim 4, wherein the designated format comprises:

numerals of a character row for using a title search method;

numerals of a numeral row for using a phone number search method; and

a specific word for using an address search method.

6. The quick search device of claim 4, wherein when the designated format corresponding to the search word does not exist, the quick search display unit receives an input of a search method, and the search unit searches for a destination based on a search method in which the quick search display unit receives.

7. The quick search device of claim 6, wherein the quick search display unit displays a search method corresponding to the designated format and receives an input of a search method using a search method toggle that can select a search method when the search method is selected.

8. The quick search device of claim 2, wherein when a turn segment exists in the path, the path display unit displays lane information of a road corresponding to a position of the path display terminal and distinguishes a lane that can turn from other lanes in the lane information and displays the lane.

9. The quick search device of claim 8, wherein when the path display unit displays lane information, the quick search display unit converts a quick search area to a quick search button and displays the quick search button.

10. A method of performing a quick search of a path display terminal, the method comprising:

displaying a position of the path display terminal on a map generated based on map data;

displaying a quick search area in a portion of the map;

inputting a search word to the quick search area;

searching for a destination corresponding to the search word;

generating a path from the position of the path display terminal to the destination and displaying the path;

measuring a moving speed of the path display terminal; and

changing transparency to allow the portion of the map, on which the quick search area is positioned, to be seen through the quick search area in correspondence to the measured moving speed of the path display terminal.

11. The method of claim 10, wherein the quick search area displays, along a line, a window for inputting a search word and a search execution button.

12. The method of claim 10, wherein the changing of transparency of the quick search area comprises increasing, if a moving speed of the path display terminal is larger than or equal to a reference speed, transparency of the quick search area and decreasing, if a moving speed of the path display terminal is less than a reference speed, transparency of the quick search area.

13. The method of claim 10, wherein the searching for of a destination comprises:

determining whether a search word is input in a designated format to the quick search area;

displaying a search method corresponding to the designated format; and

searching for the destination based on the search method.

14. The method of claim 13, wherein the designated format comprises:

numerals of a character row for using a title search method;

numerals of a numeral row for using a phone number search method; and

a specific word for using an address search method.

15. The method of claim 13, wherein the searching for of the destination further comprises:

receiving an input of a search method; and

searching for the destination based on the received search method.

16. The method of claim 15, wherein the receiving of an input of a search method comprises:

displaying a search method corresponding to the designated format; and

receiving, when the search method is selected, an input of the search method using a search method toggle that can select the search method.

17. The method of claim 10, wherein the generating a path from the position of the path display terminal to the destination and displaying the path comprises displaying, when a turn segment exists in the path, lane information of a road corresponding to a position of the path display terminal and distinguishing a lane that can turn from other lanes in the lane information and displaying the lane.

18. The method of claim 17, wherein the displaying of a quick search area in a portion of the map comprises converting, when lane information is displayed on the map, the quick search area to a quick search button and displaying the quick search button.
